Research Chairs 2024
Prof Paul Oberholster, Dean: NAS; Dr Glen Taylor, Senior Director for the Directorate Research Development (DRD); Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation; and Prof Johan van Niekerk, Vice-Dean for Agriculture in the Faculty of Natural and Agricultural Sciences (NAS); are excited for the new ARC-DALLRD-UFS research chairs.

In a concerted effort to address the challenges and impact of climate change in Southern Africa, the University of the Free State (UFS) together with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD) established four new research chairs within the Faculty of Natural and Agricultural Sciences (NAS).

The ARC-DALLRD-UFS research chairs, namely Climate Change and Agriculture, Innovative Agro-processing for Climate-smart Food System, Agriculture Risk Financing and Sustainable Livestock Production, falls under the umbrella of climate change and are part of the established centre of excellence of the ARC and DALRRD on Climate Smart Agriculture.

They will form part of two centres of excellence that the university is also in the process of establishing. The framework for these Agriculture Research Centres of Excellence involves several key components aimed at fostering innovation, collaboration, and impactful research in agriculture. In this case it is Climate Smart Agriculture, enabling them to play a pivotal role in advancing agriculture, enhancing productivity, sustainability, and resilience in the face of global challenges related to climate change.

Prof Johan van Niekerk, Vice-Dean for Agriculture for NAS, and Prof Sonja Venter, from the ARC, are the coordinators for the ARC-UFS-consortium. Joel Mamabolo from the DALRRD is the department’s representative and DALRRD manager in the consortium.

The purpose of the research chairs, he explains, is to conduct high-level research with an aspect of community impact as envisaged in the university’s vision 130. This is the UFS and NAS’s first steps towards creating industry chairs with negotiations between the UFS and the ARC-DALRRD currently taking place for further expansion of the chairs.

Improve research and food security

“The UFS has a long-standing relationship with the ARC and the parties came together to work together to improve research and food security in South Africa and Sub-Saharan Africa. The best way to do this, was by creating research chairs. The ARC saw the university’s expertise in agriculture which also contributed to the ARC establishing the chairs. Our expertise is of such a nature that it does not only influence the sector, but also makes a lasting difference,” says Prof Van Niekerk.

According to him, the ARC and the UFS will collectively manage the research chairs by appointing co-chair principal scientists for each of the chairs in order for the chairs to work together and share resources and expertise. The ARC-DALLRD-UFS research chairs will also work closely together within multidisciplinary research teams and complement each other and in doing so, create a value chain within the agriculture sector.

It will integrate various disciplines including agronomy, genetics, soil science, ecology, pathology economics, socioeconomics horticulture, animal sciences, food sciences and engineering to mention a few. This multidisciplinary approach will foster comprehensive research solutions and innovation at the intersection of different fields and will aim to contribute to sustainable food systems for the future.

The first two chairs; Climate Change and Agriculture, headed by Prof Linus Franke, Head of the UFS Department of Soil, Crop, and Climate Sciences, and the Innovative Agro-processing for Climate-smart Food System, which will be under Dr Alba du Toit, Senior Lecturer in the Department of Sustainable Food Systems and Development, officially started on 1 July 2024, while the remaining two chairs will begin operating in December. The ARC will soon confirm the co-leaders of the various chairs.

The Agriculture Risk Financing research chair will be shared between the Department of Agricultural Economics, within NAS, and the UFS Business School. The Sustainable Livestock Production chair will fall within Prof Frikkie Neser’s Department of Animal Science. To add more credibility, experience and expertise to the ARC-DALLRD-UFS research chairs, Prof Maryke Labuschagne, who is leading the NRF SARChI Chair in Diseases and Quality of Field Crops, has been appointed as mentor.

Prof Vasu Reddy, Deputy Vice-Chancellor, Research and Internationalisation, says: “These chairs mark an exciting opportunity to deepen our understanding of climate change aligned to our expertise in agriculture. The chairs offer us the opportunity to honour and support the leaders who will contribute in powerful ways to the vibrant intellectual life of the faculty, as well as the university, the ARC and DALRRD.

“The chairs also honour the donor whose financial support makes this form of recognition possible. At the UFS we are committed to engaging in global challenges but with a deliberate local focus, energy and drive. I am especially excited that these chairs demonstrate a commitment to the UFS focus on partnerships with industry, communities, the state and other academic and research institutions both nationally and around the world.”

Grateful for the ARC relationship

Through these chairs more collaborators and partners from other universities in the country and globally will be included in the partnership with the aim to bring together internationally renowned scientific experts that will collectively focus to address global challenges and enhance the development of more scientific capacity for the country.

The university, Prof Van Niekerk continues, is grateful for the cooperation and relationship with the ARC and its President and CEO, Dr Litha Magingxa and the executive management team, as well as the DALRRD DG, Mooketsa Ramasodi and the DDG for Agricultural Production, Biosecurity and Natural Resources Management, Dipepeneneng Serage for creating an environment within which the Universities and ARC can collectively contribute towards developing solutions with the DALRRD for key agricultural challenges of the country.

He expressed his gratitude to the Directorate Research Development (DRD) under the leadership of Dr Glen Taylor, for not only their support, but for bringing the parties together and negotiating with the ARC on their behalf. In this regard he wishes to thank Dr Petronella Chaminuka from the ARC as the acting Executive Manager: Research support and coordination for her support, guidance and leadership during the process.

Prof Van Niekerk also thanked Profs Francis Petersen, UFS Vice-Chancellor and Principal, Reddy, and Paul Oberholster, Dean of the Faculty of NAS, for creating the environment and rendering immense support for this programme from the UFS.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
